Scientists Discover Huge Amounts of Aluminum In The Brains of Deceased Autistic People

Scientists have been aware of aluminum’s neurotoxicity for decades. Although aluminum’s apologists have tried to shroud the metal’s risks in manufactured controversy, a growing number of reports by researchers in the United Kingdom, France, Canada, Israel, the U.S. and elsewhere has furnished substantive evidence linking aluminum to neuropathology, including the epidemics of Alzheimer’s disease (AD) and autism spectrum disorder (ASD).

Aluminum levels were particularly high in the male brains, including in a 15-year-old boy with ASD who had the study’s single highest brain aluminum measurement.

Dr. Christopher Exley—one of the world’s leading experts on aluminum toxicity—has shown that chronic intoxication with myriad forms of this “ubiquitous and omnipresent metal” is exacting a high price on human health. Dr. Exley and other aluminum experts such as molecular biologist Dr. Lucija Tomljenovic have confirmed that aluminum readily and actively traverses the blood-brain barrier to selectively accumulate in brain tissues, where it induces unwelcome changes in brain biochemistry. As Dr. Exley has noted, “There are no ‘normal’ levels of brain aluminum,” meaning that “its presence in brain tissue, at any level, could be construed as abnormal” [emphasis added].

Documenting Aluminum in the ASD Brain

In light of the fact that even minute amounts of aluminum can have adverse neurological consequences, Dr. Exley’s newest paper—which reports on the first-ever study of aluminum in ASD brain tissue—is groundbreaking. Published in the Journal of Trace Elements in Medicine and Biology, the paper documents some of the highest values for aluminum in human brain tissue ever recorded. Using a two-pronged study design (see box), the researchers measured and characterized aluminum deposits in brain tissues from five to ten ASD donors, most of whom died in their teens or twenties.
